Description
Model 347’s are found in oil and gas, hydraulic control, test and many other applications requiring stable and reliable pressure measurements with good accuracy at a fair price. They can be configured in a variety of ways – from a sealed housing with a cable to allow it to be used in outdoor environments to a unit ranged to allow for high pressure spikes with a solid machined diaphragm. We welcome your inquiries to provide you with a solution tailored to your needs.
